This is accomplished by means .of asprocket ychain 27 passingover -alsprocketj 28 on one of the rolls 6.

Intermediate the bearing 23 'andy the swivels 20 is'ra worm-1 wheel 31 vkeyed tothe spindle19 andgsurrounded bythe gear casing 32. l 'y This gear casing'falso acts 'asafjournalyfor .f a worm- (Fig-1^) lyingto lone side ofthe worm yWheel'and driven from a stub`shaft.33.

through the intermediary of the bevel gearing 39, the shaft 40, the bevel gearing 41, the shaft 40a and the bevel gears 41a. The roll 4, whose driven en-d lies at the opposite side of the machine, is similarly driven by suitable gearing including an extension of the shaft'40 andthe bevel gearing 42. Y i

The gear casing 32 is supported by means of alink V43 pivoted at 44 at its upper end 'to thefbgearing 45,`whi'ch carriesthe shafty 36. The' lower end of the link is connected to the gear casing by a ball joint 46.

The ball joint connection 46 vpermits the casing 32 to adjust itself tothe movement of the outer end of the spindle 19. Due to the fact that the rolls 3 and 4 Vare necessarily -of small `diameter due to considerations recog n-ized inthe art, there is a tendency of these rolls to warpA orsag slightly, which results in a wobbling` action of the outer ends of the Unless provision is made for thiswo'bbling action, binding occurs and undue wear upon the driving `mechanism. The mounting of the casing as above vdescribed taltves care of this condition. This condition is lalso taken care of in so far as the drive is 'concerned by the use of the universal joints 35 andl37 and the sliding engagement of the shaft 34 with the lower member of the universal joint 37. The location of the bearings 23 relatively close to the body portions of the rolls is advantageous as it reduces the tendency of lthe rolls to sag or de'iiect between the bearings. The deflection is in part due to the weight ofthe rolls and in part to the pressure exerted bythe glass between the rolls which tendsto `spread them and give a sheet of unequal thickness.I The bearings are preferably water cooled in order to protect the'm fromthe heat, althoughthis may be dispensed with in some cases. `Furbearings engaging the spindles adjacent the body portion of the roll,'a`driving gear on one of said spindles outward of the bearing von Vsuc'h spindle, a lgear casing: mounted on the *spindle around `said gear, a support for thecasing permitting universal movement.
